Light Pollution
Brightening of the night sky caused by street lights and other man-made sources, which has a disruptive effect on natural cycles and inhibits the observation of stars and planets.
Light pollution is the over illumination of an area that is considered obtrusive. Sources include:
- Large cities
- Billboards and advertising
- Nighttime sporting events and other nighttime entertainment
Light pollution makes it impossible to see stars, therefore interfering with astronomical observation and personal enjoyment. If it is near residential areas, light pollution can also degrade the quality of life for residents.
